Perhaps this could be considered, when/if implementing a more generic brute force framework as proposed by Martin Swende [1] ?I agree that a brute force library/framework or is the way to go, especially as the scripts get more complex due to parallelisms and algorithm optimizations. That being said, it sometimes is easiest to start with one script and experiment/benchmark to figure out what works best. Then that can be ported to a new generalized library. In other cases (or for other people), starting with the generalized library is easier.
It seems to me this is something best handled in the NSock Lua binding. That is, if a server is "misbehaving" by slowing down replies or dropping connections then we should lower the parallelism against the server? This is probably too low level though. That said, I'm curious why the parallel implementation performed so poorly. Patrik, do you know how the server was reacting? Was it dropping connections? Slowing down replies? How does your db2.lua library handle dropped connection attempts? Does it retry? -- - Patrick Donnelly _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
